I am sorry if a similar question has already been asked, but I'm not exactly sure what to search for to find what I am trying to accomplish.

When you type in texmaker, say for instance, \begin(x) it automatically fills in \end(x), which is obviously very useful, but I would like to know if it is possible to extend this autocomplete functionality.

I would like to edit the auto complete for \include(figure) to automatically add other sections which I always add as follows

Hi, I use Texmaker 5.0.2 (latest version Windows 10. When I write down the code, for instance, \begin{document} , then \end{document} will be automatically filled in. Which version of Texmaker do you use? Good luck.
